Let's define the number of cars received by each supplier:
- First supplier: 1,000,000 cars.
- Second supplier: 500,000 more than the first supplier = 1,000,000 + 500,000 = 1,500,000 cars.
- Third supplier: same as first + second supplier = 1,000,000 + 1,500,000 = 2,500,000 cars.
- Fourth and fifth suppliers: Let each receive X cars. They're equal.
Total distributed:
1,000,000 (first) + 1,500,000 (second) + 2,500,000 (third) + X (fourth) + X (fifth) = 5,650,000
Add up the known amounts:
1,000,000 + 1,500,000 + 2,500,000 = 5,000,000
So,
5,000,000 + 2X = 5,650,000
2X = 650,000
X = 325,000
So, the fourth and fifth suppliers each receive 325,000 cars.
